ASSIGNMENT AND SUBLETTING

(b) Without limiting the foregoing, any agreement pursuant to which: (x) Subtenant is relieved from the obligation to pay, or a third party agrees to pay on Subtenant’s behalf, all or any portion of Basic Rent, Escalation Charges or other charges due under this Sublease; and/or (y) a third party undertakes or is granted the right to assign or attempt to assign this Sublease or sublet or attempt to sublet all or any portion of the Subleased Premises, shall for all purposes hereof be deemed to be an assignment of this Sublease and subject to the provisions of this Article VI. Unless the stock or partnership interest (or other evidence of the ownership of Subtenant) is registered and publicly traded on an exchange regulated by the United States Securities and Exchange Commission, the provisions of this paragraph (a) shall apply to a transfer (by one or more transfers over the Sublease Term) of fifty one percent (51%) or more of the stock or partnership interests or other evidences of ownership of Subtenant as if such transfer were a prohibited assignment of this Sublease.

(c) If, in violation of this Article 6, this Sublease be assigned, or if the Subleased Premises or any part thereof be sublet or occupied by anyone other than Subtenant and there is an Default of Subtenant, Sublandlord may, at any time and from time to time, collect rent and other charges from the assignee or occupant, and apply the net amount collected to the rent and other charges herein reserved, but no such assignment, subletting, occupancy, collection or modification of any provisions of this Sublease shall be deemed a waiver of this covenant, or the acceptance of the assignee or occupant as a Subtenant or a release of Subtenant from the further performance of covenants on the part of Subtenant to be

9

performed hereunder. Any consent by Sublandlord to a particular subletting or occupancy shall not in any way diminish the prohibition stated in paragraph (a) of this Section 6.1 or the continuing liability of the original named Subtenant. No assignment or subletting hereunder shall relieve Subtenant from its obligations hereunder and Subtenant shall remain fully and primarily liable therefor. No such assignment, subletting, or occupancy shall affect or be contrary to Permitted Uses. Any consent by Sublandlord to a particular assignment, subletting or occupancy shall be revocable, and any assignment, subletting or occupancy shall be void ab initio, if the same shall fail to require that such assignee or occupant agree therein to be independently bound by and upon all of the covenants, agreements, terms, provisions and conditions set forth in this Sublease on the part of Subtenant to be kept and performed.

(d) If Sublandlord (and Master Landlord to the extent required under the Master Lease), consents to Subtenant’s assignment of this Sublease or further sublease of the Subleased Premises at a rental or for other consideration in excess of the Rent due and payable by Subtenant under this Sublease, then Subtenant shall pay to Sublandlord, as “Additional Rent”: (a) on the first day of each month during the term of any such sublease or assignment, fifty percent (50%) of the excess of all rent and other consideration received from the sub-subtenant or assignee for such month over the Rent then payable to Sublandlord pursuant to the provisions of this Sublease for said month (or if only a portion of the Subleased Premises is being sublet, the excess of all rent and other consideration due from the sub-subtenant for such month over the portion of the Rent then payable to Sublandlord pursuant to the provisions of this Sublease for said month), after deducting Subtenant’s reasonable, out-of-pocket transaction costs for brokerage commissions, legal fees, tenant improvements, and free rent. Notwithstanding the foregoing, this sharing of profits shall not apply to Permitted Transfers.

ARTICLE VII

10

(b) If repairs are required to be made by Subtenant pursuant to the terms hereof, Sublandlord may demand that Subtenant make the same forthwith, and if Subtenant refuses or neglects to commence such repairs and complete the same with reasonable dispatch, after such demand (except in the case of an emergency, in which event Sublandlord may make such repairs immediately), Sublandlord may (but shall not be required to do so) make or cause such repairs to be made (the provisions of Section 14.18 being applicable to the costs thereof), and shall not be responsible to Subtenant for any loss or damage whatsoever that may accrue to Subtenant’s stock or business by reason thereof.

11

(b) If any such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling, Subtenant agrees to employ only persons holding a Master ▇▇▇▇▇▇’s License to do such work, and that all work in connection therewith shall comply with applicable laws and regulations. Any such moving shall be at the sole risk and hazard of Subtenant, and Subtenant will exonerate, indemnify and save Sublandlord harmless against and from any liability, loss, injury, claim or suit resulting directly or indirectly from such moving.

MISCELLANEOUS PROVISIONS

20

(b) No payment by Subtenant, or acceptance by Sublandlord, of a lesser amount than shall be due from Subtenant to Sublandlord shall be treated otherwise than as a payment on account of the earliest installment of any payment due from Subtenant under the provisions hereof. The acceptance by Sublandlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Sublandlord may accept such check (whether or not with knowledge of any breach by Subtenant) without prejudice to any other rights or remedies which Sublandlord may have against Subtenant.

(a) In no event shall Sublandlord ever be liable to Subtenant for any loss of business or any other indirect, punitive or consequential damages suffered or claimed by Subtenant from whatever cause.

(b) Where provision is made in this Sublease for Sublandlord’s consent and Subtenant shall request such consent and Sublandlord shall fail or refuse to give such consent, Subtenant shall not be entitled to any damages for any withholding by Sublandlord of its consent, it being intended that Subtenant’s sole remedy shall be an action for specific performance or injunction, and that such remedy shall be available only in those cases where Sublandlord has expressly agreed in writing not to unreasonably withhold its consent. Any claim, demand, right or defense by Subtenant that arises out of this Sublease or the negotiations which preceded this Sublease shall be barred unless Subtenant commences an action thereon, or interposes a defense by reason thereof, within six (6) months after the date of the inaction, omission, event or action that gave rise to such claim, demand, right or defense.

21

(c) With respect to any repairs or restoration which are required or permitted to be made by Sublandlord, the same may be made during normal business hours and Sublandlord shall have no liability for damages to Subtenant for inconvenience, annoyance or interruption of business arising therefrom. In the course of any such activity, ▇▇▇▇▇▇▇▇▇▇▇ agrees to use commercially reasonable efforts not to unreasonably interfere with Subtenant’s business operations in the Subleased Premises.

(d) In no event shall Subtenant have the right to terminate this Sublease as a result of Sublandlord’s default under or breach of this Sublease, and Subtenant’s remedies shall be limited to damages and/or an injunction as expressly set forth above. This Sublease and the obligations of Subtenant hereunder shall not be affected or impaired because Sublandlord is unable to fulfill any of its obligations hereunder or is delayed in doing so, if such inability or delay is caused by reason of a Force Majeure event, and the time for Sublandlord’s performance shall be extended for the period of any such delay. Each provision of this Sublease constitutes an independent covenant, enforceable separately from each other covenant hereof. To the extent any provision hereof or any application of any provision hereof may be declared unenforceable, such provision or application shall not affect any other provision hereof or other application of such provision. Subtenant acknowledges and agrees that Subtenant’s obligation to pay Basic Rent and Escalation Charges is independent of any and all obligations of Sublandlord hereunder.

(b) In no event shall the acquisition of Sublandlord’s interest in the Building or the Park by a purchaser which, simultaneously therewith, leases Sublandlord’s entire interest in the Building or the Park (as the case may be) back to the seller thereof be treated as an assumption by operation of law or otherwise, of Sublandlord’s obligations hereunder, but Subtenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Sublandlord’s obligations hereunder. In any such event, this Sublease shall be subject and subordinate to the Sublease to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the Sublandlord hereunder unless and until Sublandlord’s position shall have been assumed by such purchaser-lessor.

22

(c) Except as provided in paragraph (b) of this Section, in the event of any transfer of title to the Building by Sublandlord, Sublandlord shall thereafter be entirely freed and relieved from the performance and observance of all covenants and obligations hereunder.

23

(b) This Sublease may be executed in one or more counterparts, and by different parties hereto on separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. The parties acknowledge and agree that this Sublease may be executed via facsimile or .pdf format (including computer-scanned or other electronic reproduction of the actual signatures) and that delivery of a facsimile or other signature by electronic or physical means shall be effective to the same extent as delivery of an original signature. Notwithstanding the foregoing, originally signed documents shall be provided upon either party’s request.

ARTICLE VI

- 12 -

(b) The provisions of paragraph (a) shall not apply to assignments or subleases of this Lease arising from or in connection with either: transactions with an entity into or with which Tenant is merged or consolidated, or to which substantially all of Tenant’s assets are transferred; or transactions with any entity which controls or is controlled by Tenant or is under common control with Tenant; provided that in either such event:

(i) the successor to Tenant or sublessee has a net worth computed in accordance with generally accepted accounting principles consistently applied at least equal to the greater of (1) the net worth of Tenant (together with that of any guarantor(s)) immediately prior to such merger, consolidation or transfer, or (2) the net worth of Tenant (together with that of any guarantor(s)) herein named on the date of this Lease,

(ii) proof satisfactory to Landlord of such net worth shall have been delivered to Landlord at least 10 days prior to the effective date of any such transaction, and

(iii) the assignee or sublessee agrees directly with Landlord, by written instrument in form satisfactory to Landlord, to be bound by all the obligations of Tenant hereunder including, without limitation, the covenant against further assignment and subletting.

Any consent by Landlord to a particular subletting or occupancy shall not in any way diminish the prohibition stated in paragraph (a) of this Section 6.1 or the continuing liability of the original named Tenant. No assignment or subletting hereunder shall relieve Tenant from its obligations hereunder and Tenant shall remain fully and primarily liable therefor No such assignment, subletting, or occupancy shall affect or be contrary to Permitted Uses. Any consent by Landlord to a particular assignment, subletting or occupancy shall be revocable, and any assignment, subletting or occupancy shall be void ab initio, if the same shall fail to require that such assignee, subtenant or occupant agree therein to be independently bound by and upon all of the covenants, agreements, terms, provisions and conditions set forth in this Lease on the part of Tenant to be kept and performed.

- 13 -

(i) The business of each proposed subtenant and its use of the Premises shall be consistent with the Permitted Uses, and the financial condition and standing of the proposed subtenant shall be reasonably acceptable to Landlord (notwithstanding that Tenant will remain liable hereunder)..

(ii) Neither the proposed subtenant nor any person who directly or indirectly, controls, is controlled by, or is under common control with, the proposed subtenant or any person who controls the proposed subtenant, shall be (A) a government (or subdivision or agency thereof), or (B) a medical or dental office, or (C) a tenant of the Building or the Park;

(iii) The form of the proposed sublease, as well as the Landlord’s consent thereto, shall be reasonably satisfactory to Landlord and its counsel and shall comply with the applicable provisions of this Article 6;

(iv) not later than fifteen (15) days prior to the proposed commencement of such sublease, Landlord shall have received information reasonably sufficient to determine compliance with the foregoing conditions; and

(v) Tenant shall in all cases remain fully and primarily liable hereunder.

If Tenant requests ▇▇▇▇▇▇▇▇’s consent to a sublease then, at the time of such request, Tenant shall provide Landlord with a written description of all terms and conditions of the proposed transfer, copies of the proposed documentation, and the following information about the proposed sublessee: name and address; reasonably satisfactory information about its business and business history; its proposed use of the Premises; banking, financial, and other credit information; and general references sufficient to enable Landlord to determine the proposed sublessee’s creditworthiness and character.

(b) It shall not be unreasonable for Landlord to withhold its consent to any proposed sublease if (i) at the time of such request, Tenant is in default under this Lease, (ii) the proposed sublessee is a tenant in the Building or is an affiliate of such a tenant or a party that Landlord has identified as a tenant or a prospective tenant in the Building, (iii) the financial responsibility (including, without limitation, the fact that the proposed sublessee has a smaller net worth than tenant on the date of this Lease and/or such sublessee is less able financially to pay the Rent under this Lease as and when they are due and payable),

- 14 -

nature of business, and character of the proposed transferee are not all reasonably satisfactory to Landlord, (iv) in the reasonable judgment of Landlord the purpose for which the transferee intends to use the Premises (or a portion thereof) is not in keeping with Landlord’s standards for the Building or would impose a burden on the parking facilities, elevators, Common Areas or utilities that is greater than the burden imposed by Tenant (or, in the case of retail space, is for a use that Landlord determines in its sole discretion is inconsistent with Landlord’s desired retail mix), (v) the proposed sublessee is a government entity or quasi-governmental entity or agency, (vi) the Basic Rent payable by the proposed transferee is less than the greater of: (x) the then prevailing fair market rental rate for the Premises as determined by Landlord, or (y) the Basic Rent payable by Tenant under the Lease and/or (vii) the proposed sublease would cause Landlord to be in violation of any of its obligations under another lease or agreement to which Landlord is a party. In no event shall any sublease cover fewer than 2,000 square feet of space or have a fixed term of less than one (1) year. The foregoing shall not exclude any other reasonable basis for Landlord to withhold its consent. Landlord shall have no liability for damages to Tenant or to any proposed sublessee, and Tenant shall not be permitted to terminate this Lease, if it is adjudicated that Landlord’s consent has been unreasonably withheld and such unreasonable withholding of consent constitutes a breach of this Lease or other duty to Tenant, the proposed sublessee or any other person on the part of Landlord. In such event, ▇▇▇▇▇▇’s sole remedy shall be to have the proposed sublease declared valid as if ▇▇▇▇▇▇▇▇’s consent had been given.

- 15 -

(b) Notwithstanding any sublease, or any amendments or modifications subsequent thereto, Tenant will remain fully liable for the payment of Basic Rent, Escalation Charges and other charges and for the performance of all other obligations of Tenant contained in this Lease.

- 17 -

(b) If repairs are required to be made by Tenant pursuant to the terms hereof, Landlord may demand that Tenant make the same forthwith, and if Tenant refuses or neglects to commence such repairs and complete the same with reasonable dispatch, after such demand (except in the case of an emergency, in which event Landlord may make such repairs immediately), Landlord may (but shall not be required to do so) make or cause such repairs to be made (the provisions of Section 14.18 being applicable to the costs thereof), and shall not be responsible to Tenant for any loss or damage whatsoever that may accrue to Tenant’s stock or business by reason thereof.

- 18 -

(b) If any such safe, machinery, equipment, freight, bulky matter or fixtures requires special handling, Tenant agrees to employ only persons holding a Master ▇▇▇▇▇▇’s License to do such work, and that all work in connection therewith shall comply with applicable laws and regulations. Any such moving shall be at the sole risk and hazard of Tenant, and ▇▇▇▇▇▇ will exonerate, indemnify and save Landlord harmless against and from any liability, loss, injury, claim or suit resulting directly or indirectly from such moving.

(b) Landlord will use reasonable efforts upon reasonable advance written notice from Tenant of its requirements in that regard, to furnish additional heat, cleaning or air conditioning services to the Premises on days and at times other than as set forth in Section 7.4(a) (“the Overtime Hours”). Tenant will pay to Landlord, as Additional Rent, for any such additional heat, cleaning or air conditioning service required by Tenant for the Overtime Hours. The cost for any HVAC service during Overtime Hours requested by ▇▇▇▇▇▇ and provided by Landlord is currently $75.00 per hour per HVAC unit.

If and to the extent that Tenant desires to provide security for the Premises or for such persons or their property, Tenant shall be responsible for so doing, after having first consulted with Landlord and after obtaining ▇▇▇▇▇▇▇▇’s consent, which shall not be unreasonably withheld. Landlord expressly disclaims any and all responsibility and/or liability for the physical safety of Tenant’s property, and for that of Tenant’s employees, agents, contractors and invitees, and, without in any way limiting the operation of Article X hereof, Tenant, for itself and its agents, contractors, invitees and employees, hereby expressly waives any claim, action, cause of action or other right which may accrue or arise as a result of any damage or injury to the person or property of Tenant or any such agent, invitee, contractor or employee ▇▇▇▇▇▇ agrees that, as between Landlord and Tenant, it is Tenant’s responsibility to advise its employees, agents, contractors and invitees as to necessary and appropriate safety precautions.

(f) Notwithstanding the foregoing to the contrary, if, due to any negligent or willful and wrongful act or omission of Landlord or Landlord’s agents or employees, Tenant is prevented from receiving essential services or utilities that Landlord is obligated to perform or deliver under this Lease, and such interruption of essential services or utilities renders the Premises untenantable (meaning that Tenant is unable to use and occupy the Premises in a reasonably safe manner for the business office purposes and Tenant has in fact vacated or partially vacated the Premises as a result), and if such interruption shall continue for a period of five (5) consecutive Business Days after notice thereof from Tenant to Landlord that the Premises are untenantable as a result thereof, then Basic Rent and additional rent shall ▇▇▇▇▇ commencing on the sixth Business Day after such notice (and, if less than all of the Premises are affected by such interruption and vacated, such abatement shall be pro-rated according to the area so affected) until such time as such services or utilities are restored. The foregoing shall not apply to any interruption to the extent the same arises from any act or omission of Tenant or its agents, contractors or employees, or from fire or casualty, Force Majeure or taking or condemnation by the power of eminent domain, which are dealt with in Article XII. Tenant’s rights herein granted shall be Tenant’s sole and exclusive remedies for any loss or damage arising from any such interruption.

- 21 -

(b) From time to time during the Term of this Lease, Landlord shall have the right to have an electrical consultant selected by Landlord make a survey of Tenant’s electric usage, the result of which survey shall be conclusive and binding upon Landlord and Tenant. In the event that such survey shows that Tenant has exceeded the requirements set forth in paragraph (a), in addition to any other rights Landlord may have hereunder, Tenant shall, upon demand, reimburse Landlord for the cost of such survey and the cost, as determined by such consultant, of electricity usage in excess of such requirements for the period of such excess usage, as additional charges.

(c) Tenant acknowledges that Basic Rent does not include the cost of Tenant’s electricity, which cost shall be determined as provided in this paragraph.

(i) If the electricity usage in the Premises is not separately metered or sub-metered, Tenant shall pay for the electricity Tenant consumes in the Premises during the Term (exclusive of HVAC) by paying Landlord, as Additional Rent, at the same time and in the same manner as Tenant pays its monthly installment of Basic Rent hereunder, estimated amounts (the “Electricity Rent”) on account of electricity consumed in the Premises. As of the date hereof, the Electricity Rent payable by Tenant is an amount per annum equal to $2.00 times the Rentable Floor Area of the Premises. The Electricity Rent shall be reasonably adjusted by Landlord from time to time based on current rates for such service and Landlord’s good faith estimate of the usage of electricity by occupants of the Building If Landlord determines that the actual cost of providing electricity to the Premises exceeds the Electricity Rent, Landlord may (i) increase the Electricity Rent accordingly, or (ii) elect to separately meter or submeter electric service to the Premises, at Tenant’s expense.

(ii) If the electric usage in the Premises is measured by a direct meter, such meter will include all convenience electricity as well as any air handling units or other HVAC equipment located within the Premises, and Tenant shall pay directly to the provider thereof, on or before the date when due and in addition to payments of Basic Rent and other additional rent provided for herein, the costs of all electricity used in the Premises.

(iii) If Landlord measures electricity or any other utility usage in the Premises by a submeter, such submeter will include all convenience electricity as well as any air handling units or other HVAC equipment located within the Premises, and Tenant shall pay the costs as shown on such submeter to Landlord (and at the rate or rates payable by Landlord to the applicable utility), as additional rent, within thirty (30) days after receipt of an invoice therefor.

(iv) If electricity or other services to the Premises are separately metered, and Tenant pays directly to the providing utility company(ies), Landlord shall have the right to require Tenant to provide Landlord with copies of bills from electricity, natural gas or similar energy providers (collectively, “Energy Providers”) that Tenant receives from Energy Providers relating to Tenant’s energy use at the Premises (“Energy Bills”) within ten (10) Business Days after Landlord’s written request. In addition, Tenant hereby authorizes Landlord to obtain copies of the Energy Bills directly from the Energy Provider(s), and Tenant hereby authorizes each Energy Provider to provide Energy Bills and related usage information directly to Landlord without ▇▇▇▇▇▇’s consent. From time to time within ten (10) Business Days after Landlord’s request, ▇▇▇▇▇▇ shall execute and deliver to Landlord an agreement provided by Landlord authorizing the Energy Provider(s) to provide to Landlord Energy Bills and other information relating to ▇▇▇▇▇▇’s energy usage at the Premises. Landlord acknowledges that the information provided by the Energy Providers shall be used by Landlord in connection with ▇▇▇▇▇▇▇▇’s on-going energy and environmental conservation initiatives.

Tenant acknowledges that, in addition to the Electricity Rent, the Tenant shall pay its pro-rata share of the cost of furnishing electricity for the Building’s common areas (including without limitation the cost of furnishing electricity for the cooling tower and tempering and circulating condenser water) and elevators as part of Operating Expenses. In any event, Tenant shall also pay separately for all telephone and any other utilities and services supplied and/or metered exclusively to the Premises or to Tenant, together with any taxes thereon.

(d) Tenant shall not at any time contract to purchase electricity from any provider other than the service provider from whom Landlord from time to time shall purchase electricity for the common areas of the Building, or give any such provider permission to install lines or other equipment, without in each case obtaining the Landlord’s prior written consent. Landlord shall have no liability for the service to be provided by any provider, including without limitation any loss or interruption of service or any damages to Tenant or its business arising therefrom.

REAL ESTATE TAXES

- 23 -

(b) In the event that for any reason, Taxes during any Tax Year shall exceed Base Taxes, Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) the excess of Taxes over Base Taxes for such Tax Year, multiplied by (ii) the Escalation Factor, such amount to be apportioned for any portion of a Tax Year in which the Commencement Date falls or the Term of this Lease ends.

(c) Estimated payments by Tenant on account of Taxes shall be made on the first day of each and every calendar month during the Term of this Lease, and otherwise in the fashion herein provided for the payment of Basic Rent. The monthly amount so to be paid to Landlord shall be sufficient to provide Landlord by the time real estate tax payments are due with a sum equal to ▇▇▇▇▇▇’s required payments, as estimated by Landlord from time to time, on account of Taxes for the then current Tax Year. Promptly after receipt by Landlord of bills for such Taxes, Landlord shall advise Tenant of the amount thereof and the computation of Tenant’s payment on account thereof. If estimated payments theretofore made by Tenant for the Tax Year covered by such bills exceed the required payments on account thereof for such Year, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant on account of Taxes (or refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord); but if the required payments on account thereof for such Year are greater than estimated payments theretofore made on account thereof for such Year, Tenant shall make payment to Landlord within 30 days after being so advised by Landlord.

(d) Tenant shall pay all taxes charged, assessed or imposed upon the personal property of Tenant in or upon the Premises.

- 24 -

(b) If a tax (other than a Federal or State net income tax) is assessed on account of the rents or other charges payable by Tenant to Landlord under this Lease, ▇▇▇▇▇▇ agrees to pay the same as an additional charge within ten (10) days after billing therefor, unless applicable law prohibits the payment of such tax by Tenant.

ARTICLE IX

OPERATING EXPENSES; UTILITIES

Operating Year: Each calendar year in which any part of the Term of this Lease shall fall.

Operating Expenses: all costs and expenses incurred for the operation, cleaning, maintenance, repair and upkeep of the Building and the Park, including, without limitation, all costs of maintaining and repairing the Building and Park (including, without limitation, security, elevators, lighting and any other Building equipment or systems) and costs to maintain an on-site management office and all costs of all repairs and replacements (other than repairs or replacements for which Landlord has received full reimbursement from other tenants of the Building or from others) necessary to

- 25 -

keep the Building and Park in good working order, repair, appearance and condition; all costs, including material and equipment costs, for cleaning and janitorial services to the Building (including window cleaning of the Building); all costs of any insurance carried by Landlord relating to the Building; all costs related to provision of heat (including oil, electric, steam and/or gas), air-conditioning, and water (including sewer charges and the private water supply company charges or assessments) and other utilities to the Building (exclusive of reimbursement to Landlord for any of same received as a result of direct billing to any tenant of the Building); payments under all service contracts relating to the foregoing; all compensation, fringe benefits, payroll taxes and workmen’s compensation insurance premiums related thereto with respect to any employees of Landlord or its affiliates, or third party management company, engaged in security and maintenance of the Building; attorneys’ fees and disbursements (exclusive of any such fees and disbursements incurred in tax abatement proceedings or the preparation of or negotiation of any leases) and auditing and other professional fees and expenses; all costs associated with those improvements, systems, signage, equipment, and installations that are designated by Landlord to serve or benefit the Park by facilitating the flow of traffic into or out of the Park, whether or not located within, adjacent to, or near the Park; and a reasonable management fee consistent with the local market in which the Building is located, not to exceed five percent (5%) of the rents for the Building, provided Operating Expenses shall not include (i) costs of capital repairs, improvements, and replacements, except to the extent specifically provided for in this Lease; (ii) expenses for tenant improvement work or allowances, inducements, and other concessions for any tenant; (iii) interest, amortization, or other payments on loans to Landlord; (iv) depreciation of the Building or other improvements; (v) ground rent; (vi) brokerage or leasing commissions; (vii) compensation paid to officers or executives of Landlord above the level of asset manager; (viii) income, gross receipts, excess profits, or franchise taxes imposed on Landlord; (ix) professional fees incurred in connection with preparing any lease (including Tenant’s lease); (x) the cost of repairs, replacements, or improvements to the extent paid for by the proceeds of insurance, or that were paid for directly by Tenant or any third party; (xi) costs arising solely from the negligence or fault of Landlord, its agents, employees, invitees, or contractors; and (xii) advertising and promotional expenses for the purpose of marketing space in the Building.

(b) If, during the Term of this Lease, Landlord shall make a capital expenditure (i) for the purpose of primarily reducing Operating Expenses, or (ii) to replace obsolete operating equipment serving the Building, or (iii) in order to conform to any changes in any applicable laws, ordinances, rules or regulations of any governmental authority with jurisdiction over the Building that are first adopted or made applicable to the Building after the date hereof, the total cost of which is not properly includible in Operating Expenses for the Operating Year in which it was made, there shall nevertheless be included in such Operating Expenses for the Operating Year in which it was made and in Operating Expenses for each succeeding Operating Year the annual charge-off of such capital expenditure. Annual charge-off shall be determined by

- 26 -

dividing the original capital expenditure plus an interest factor, reasonably determined by Landlord, as being the interest rate then being charged for long-term mortgages by institutional lenders on like properties within the locality in which the Building is located, by the number of years of useful life of the capital expenditure; and the useful life shall be determined reasonably by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of making such expenditure.

(c) If during any portion of any Operating Year (including without limitation the Base Year) for which Operating Expenses are being computed, less than ninety-five percent (95%) of the Building was occupied by tenants or if not all of such tenants were paying fixed rent or if Landlord was not supplying all tenants with the services being supplied hereunder, actual Operating Expenses incurred shall be reasonably extrapolated by Landlord to the estimated Operating Expenses that would have been incurred if ninety-five percent (95%) of the Building was occupied by tenants and all such tenants were then paying fixed rent or if such services were being supplied to all tenants, and such extrapolated amount shall, for the purposes of this Section 9.1, be deemed to be the Operating Expenses for such Operating Year. The Building is a part of the Park which contains other buildings and common areas and as such, Landlord shall allocate to the Building a proportionate share of those Operating Expenses which are incurred with respect to the Park (including, without limitation, snow removal, landscaping and grounds maintenance, operation and maintenance of the parking areas, fitness center, sidewalks, walking paths, access roads and landscaped islands located thereon, driveways, security, costs in connection with the operation of the cafeterias operated in the buildings of the Park, including subsidy programs, if any, and a management fee for the Park); provided, however, at such time as Landlord ceases to own all of the buildings in the Park, those Operating Expenses with respect to the Park shall be included as part of the common charges assessed or levied against the Building as part of the Condominium (as hereinafter defined), in which event such common charges shall be allocated in accordance with Section 14.27 below.

- 27 -

(b) Estimated payments by Tenant on account of Operating Expenses shall be made on the first day of each and every calendar month during the Term of this Lease, and otherwise in the fashion herein provided for the payment of Basic Rent. The monthly amount so to be paid to Landlord shall be sufficient to provide Landlord by the end of each Operating Year a sum equal to ▇▇▇▇▇▇’s required payments, as estimated by Landlord from time to time during each Operating Year, on account of Operating Expenses for such Operating Year. Within a reasonable time after the end of each Operating Year, Landlord shall submit to Tenant a reasonably detailed accounting of Operating Expenses for such Year, and Landlord shall certify to the accuracy thereof. If estimated payments theretofore made for such Year by Tenant exceed Tenant’s required payment on account thereof for such Year, according to such statement, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant with respect to Operating Expenses (or refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord); but, if the required payments on account thereof for such Year are greater than the estimated payments (if any) theretofore made on account thereof for such Year, Tenant shall make payment to Landlord within 30 days after being so advised by Landlord. Landlord shall have the same rights and remedies for the non-payment by Tenant of any payments due on account of Operating Expenses as Landlord has hereunder for the failure of Tenant to pay Basic Rent.

(c) ▇▇▇▇▇▇ shall have the right to examine and review copies of ▇▇▇▇▇▇▇▇’s statements and invoices establishing Operating Expenses for any Operating Year for a period of ninety (90) days following the date that ▇▇▇▇▇▇ receives the statement of Operating Expenses for such Operating Year from Landlord. Tenant shall give Landlord not less than thirty (30) days’ prior written notice of its intention to examine such material, and such examination shall take place at such place within the continental United States as Landlord routinely maintains such books and records, unless Landlord elects to have such examination take place in another location designated by Landlord in the city and state in which the Property is located. As a condition to performing any such examination, Tenant and its examiners shall be required to execute and deliver to Landlord an agreement, in form reasonably acceptable to Landlord and Tenant, whereby ▇▇▇▇▇▇ agrees to keep confidential (except as may be necessary in connection with any legal or other proceeding to dispute Operating Expenses or except as may be

- 28 -

required by law) any information which it discovers about Landlord or the Building in connection with such examination. Such examination may be made only by a national recognized independent certified public accounting firm, or by a qualified and reputable consultant; provided however, that no examiner who is being paid on a contingent fee basis shall be permitted to conduct an examination of Landlord’s books and records under this section. All costs of the examination shall be borne by Tenant. If, pursuant to such examination, the payments made for such Operating Year by Tenant exceed ▇▇▇▇▇▇’s required payment on account thereof for such Operating Year, Landlord shall credit the amount of overpayment against subsequent obligations of Tenant with respect to Operating Expenses (or promptly refund such overpayment if the Term of this Lease has ended and Tenant has no further obligation to Landlord); but, if the payments made by Tenant for such Operating Year are less than Tenant’s required payment as established by such examination, Tenant shall pay the deficiency to Landlord within thirty (30) days after conclusion of the examination and audit, and the obligation to make such payment for any period within the Term shall survive expiration of the Term. If Tenant does not elect to exercise its right to examine ▇▇▇▇▇▇▇▇’s records for any Operating Year within the time period provided for by this paragraph, Tenant shall have no further right to challenge ▇▇▇▇▇▇▇▇’s statement of Operating Expenses for such Operating Year.

In addition to the insurance required in (i), (ii), (iii) and (iv) above, Landlord shall have the right to require Tenant to increase the limits of its insurance and/or obtain such additional insurance as is customarily required by landlords owning similar real property in the geographical area of the Property.

- 34 -

(vii) If: (x) Tenant shall fail to pay the Basic Rent, Escalation Charges, additional charges or other charges hereunder when due or shall fail to perform or observe any other covenant herein contained on Tenant’s part to be performed or observed and Tenant shall cure any such failure within the applicable grace period set forth in clauses (i) or (ii) above; or (y) a Default of Tenant of the kind set forth in clauses (i) or (ii) above shall occur and Landlord shall, in its sole discretion, permit Tenant to cure such Default after the applicable grace period has expired; and a similar failure or Default shall occur more than twice within the next 365 days (whether or not such similar failure is cured within the applicable grace period);

then in any such case Landlord may terminate this Lease by notice to Tenant, specifying a date not less than five (5) days after the giving of such notice on which this Lease shall terminate and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Term of this Lease, and ▇▇▇▇▇▇ will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

(C) provide Landlord with Adequate Assurance of Future Performance (as defined below) of all of Tenant’s obligations under this Lease; and

(D) deliver to Landlord a written statement that the conditions herein have been satisfied.

(ii) the trustee or the debtor-in-possession agreeing to pay in advance, on each day that the Basic Rent is payable, the monthly installments on account of Operating Expenses and Taxes, computed in accordance with Articles 8 and 9 hereof;

(iii) the trustee or debtor-in-possession providing adequate assurance of the source of the rent and other consideration due under this Lease;

- 36 -

(iv) Tenant’s bankruptcy estate and the trustee or debtor-in-possession providing Adequate Assurance that the bankruptcy estate (and any successor after the conclusion of the Tenant’s bankruptcy proceedings) will continue to have sufficient unencumbered assets after the payment of all secured obligations and administrative expenses to assure Landlord that the bankruptcy estate (and any successor after the conclusion of the Tenant’s bankruptcy proceedings) will have sufficient funds to fulfill Tenant’s obligations hereunder; and

(e) If the trustee or the debtor-in-possession assumes the Lease under paragraph (b) above and applicable bankruptcy law, it may assign its interest in this Lease only if the proposed assignee first provides Landlord with Adequate Assurance of Future Performance of all of Tenant’s obligations under the Lease, and if Landlord determines, in the exercise of its reasonable business judgment, that the assignment of this Lease will not breach any other lease, or any mortgage, financing agreement, or other agreement relating to the Building or the Park by which Landlord or the Building or the Park is then bound (and Landlord shall not be required to obtain consents or waivers from any third party required under any lease, mortgage, financing agreement, or other such agreement by which Landlord is then bound).

(f) For purposes only of paragraph (e) above, and in addition to any other requirements under the Bankruptcy Code, any future federal bankruptcy law and applicable case law, “Adequate Assurance of Future Performance” means at least the satisfaction of the following conditions, which Landlord and Tenant acknowledge to be commercially reasonable:

(ii) if requested by ▇▇▇▇▇▇▇▇ in the exercise of its reasonable business judgment, the proposed assignee obtaining a guarantee (in form and substance satisfactory to Landlord) from one or more persons who satisfy Landlord’s standards of creditworthiness;

(h) In the event of any termination, Tenant shall pay the Basic Rent, Escalation Charges and other sums payable hereunder up to the time of such termination, and thereafter Tenant, until the end of what would have been the Term of this Lease in the absence of such termination, and whether or not the Premises shall have been relet, shall be liable to

- 37 -

Landlord for, and shall pay to Landlord, as liquidated current damages: (x) the Basic Rent, Escalation Charges and other sums that would be payable hereunder if such termination had not occurred, less the net proceeds, if any, of any reletting of the Premises, after deducting all expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, legal expenses, attorneys’ fees, advertising, expenses of employees, alteration costs and expenses of preparation for such reletting; and (y) if, in accordance with Section 3.1(a), Tenant commenced payment of the full amount of Basic Rent on any day other than the Commencement Date, the amount of Basic Rent that would have been payable during the period beginning on the Commencement Date and ending on the day Tenant commenced payment of the full amount of Basic Rent under such Section 3.1(a). Tenant shall pay the portion of such current damages referred to in clause (x) above to Landlord monthly on the days which the Basic Rent would have been payable hereunder if this Lease had not been terminated, and Tenant shall pay the portion of such current damages referred to in clause (y) above to Landlord upon such termination.

(i) At any time after such termination, whether or not Landlord shall have collected any such current damages, as liquidated final damages and in lieu of all such current damages beyond the date of such demand, at ▇▇▇▇▇▇▇▇’s election Tenant shall pay to Landlord an amount equal to the excess, if any, of the Basic Rent, Escalation Charges and other sums as hereinbefore provided which would be payable hereunder from the date of such demand assuming that, for the purposes of this paragraph, annual payments by Tenant on account of Taxes and Operating Expenses would be the same as the payments required for the immediately preceding Operating or Tax Year for what would be the then unexpired Term of this Lease if the same remained in effect, over the then fair net rental value of the Premises for the same period, discounted to then net present value at 2% per annum.

(j) In case of any Default of Tenant, re-entry, expiration and dispossession by summary proceedings or otherwise, Landlord may (i) re-let the Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlord’s option be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term of this Lease and may grant concessions or free rent to the extent that ▇▇▇▇▇▇▇▇ considers advisable and necessary to re-let the same and (ii) may make such reasonable alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable and necessary for the purpose of reletting the Premises; and the making of such alterations, repairs and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to re-let the Premises, or, in the event that the Premises are re-let, for failure to collect the rent under such re-letting. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease.

- 38 -

(k) If a Guarantor of this Lease is named in Section 1.2, the happening of any of the events described in paragraphs (a)(iv)-(a)(vi) of this Section 13.1 with respect to the Guarantor shall constitute a Default of Tenant hereunder.

(l) The specified remedies to which Landlord may resort hereunder are not intended to be exclusive of any remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for.

(m) All costs and expenses incurred by or on behalf of Landlord (including, without limitation, attorneys’ fees and expenses at both the trial and appellate levels) in enforcing its rights hereunder or occasioned by any breach of this Lease by Tenant or any Default of Tenant shall be paid by ▇▇▇▇▇▇.

ARTICLE XIV

MISCELLANEOUS PROVISIONS

- 39 -

(b) No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account of the earliest installment of any payment due from Tenant under the provisions hereof. The acceptance by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check (whether or not with knowledge of any breach by Tenant) without prejudice to any other rights or remedies which Landlord may have against Tenant.

(b) With respect to any services, repairs or utilities to be furnished by Landlord to Tenant, or any other obligation to be performed by Landlord, Landlord shall in no event be liable for failure to furnish or perform the same when prevented from doing so by so-called act of god, or by strike, lockout, breakdown, accident, order or regulation of or by any governmental authority, act or threatened act of terrorism, civil commotion or unrest, governmental order or restriction or failure of ready supply, or failure whenever and for so long as may be necessary by reason of the making of repairs or changes which Landlord is required or is permitted by this Lease or by law to make or in good ▇▇▇▇▇ ▇▇▇▇▇ necessary, or inability by the exercise of reasonable diligence to obtain supplies, parts or employees necessary to furnish such services, or because of war or other emergency, or for any other cause beyond Landlord’s reasonable control (the foregoing circumstances being individually and collectively

- 40 -

referred to as “Force Majeure”), or for any cause due to any act or neglect of Tenant or Tenant’s servants, agents, employees, licensees or any person claiming by, through or under Tenant; nor shall any such failure give rise to any claim in Tenant’s favor that ▇▇▇▇▇▇ has been evicted, either constructively or actually, partially or wholly.

(c) In no event shall Landlord ever be liable to Tenant for any loss of business or any other indirect, punitive or consequential damages suffered or claimed by Tenant from whatever cause.

(d) Where provision is made in this Lease for Landlord’s consent and Tenant shall request such consent and Landlord shall fail or refuse to give such consent, Tenant shall not be entitled to any damages for any withholding by Landlord of its consent, it being intended that Tenant’s sole remedy shall be an action for specific performance or injunction, and that such remedy shall be available only in those cases where Landlord has expressly agreed in writing not to unreasonably withhold its consent. Any claim, demand, right or defense by Tenant that arises out of this Lease or the negotiations which preceded this Lease shall be barred unless ▇▇▇▇▇▇ commences an action thereon, or interposes a defense by reason thereof, within six (6) months after the date of the inaction, omission, event or action that gave rise to such claim, demand, right or defense. Furthermore, whenever Tenant requests ▇▇▇▇▇▇▇▇’s consent or approval (whether or not provided for herein), Tenant shall pay to Landlord, on demand, as an additional charge, any expenses reasonably incurred by Landlord (including without limitation legal fees and costs, if any) in connection therewith.

(e) With respect to any repairs or restoration which are required or permitted to be made by Landlord, the same may be made during normal business hours and Landlord shall have no liability for damages to Tenant for inconvenience, annoyance or interruption of business arising therefrom. In the course of any such activity, ▇▇▇▇▇▇▇▇ agrees to use commercially reasonable efforts not to unreasonably interfere with Tenant’s business operations.

(f) In no event shall Tenant have the right to terminate this Lease as a result of Landlord’s default under or breach of this Lease, and ▇▇▇▇▇▇’s remedies shall be limited to damages and/or an injunction as expressly set forth above. This Lease and the obligations of Tenant hereunder shall not be affected or impaired because Landlord is unable to fulfill any of its obligations hereunder or is delayed in doing so, if such inability or delay is caused by reason of a Force Majeure event, and the time for Landlord’s performance shall be extended for the period of any such delay. Each provision of this Lease constitutes an independent covenant, enforceable separately from each other covenant hereof. To the extent any provision hereof or any application of any provision hereof may be declared unenforceable, such provision or application shall not affect any other provision hereof or other application of such provision. ▇▇▇▇▇▇ acknowledges and agrees that Tenant’s obligation to pay Basic Rent and Escalation Charges is independent of any and all obligations of Landlord hereunder.

- 41 -

(b) In no event shall the acquisition of Landlord’s interest in the Building or the Park by a purchaser which, simultaneously therewith, leases Landlord’s entire interest in the Building or the Park (as the case may be) back to the seller thereof be treated as an assumption by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the Landlord hereunder unless and until ▇▇▇▇▇▇▇▇’s position shall have been assumed by such purchaser-lessor.

(c) Except as provided in paragraph (b) of this Section, in the event of any transfer of title to the Building by Landlord, Landlord shall thereafter be entirely freed and relieved from the performance and observance of all covenants and obligations hereunder.
